Specification of Letters Patent.

Application filed March 28, 1910. Serial No. 552,018.-

useful Im rovements in Apparatus for Bemoving 0 d Paer from Walls, of which the followmg is a ull, clear, and exact descrip tion.

This invention relates to machines for cleaningwalls andfor removing old wall paper therefrom, and it has for. one of its ob ects the provisionof an, improved apparatus of this kind in which steam is generated andconducted into atool which is applied to the wall surface and whereby the steam may be confined so as to produce the best results.

The invention has, furthermore, forits object the provision of an improved generator in which the condensation of the steam will be reduced'to a minimum and which possesses certain other features not generally found in the art. I

The invention has also for its object the combination with the steam-applying tool which may be manipulated in sucha' way as to rest flat against the wall and to find its own bearings thereon irrespective of what the position which the handle (whereby the tool is operated) may be.

Further objects of the invention will hereinafter appear and the means of their attainment be particularly ointed out in the claims.

Referring|to the drawing,'l*igure 1 renre-' sents a central vertical section of the device as a whole. Fig. 2 is a front view of the steaming tool or head of the apparatus A re resents a boiler which is referably inclose within a casing A entirely surrounding the same and forming an air-space 7 all around said boiler. Water may besupplied to the boiler A by a vertically dis posed pipe, the lower end of which terminates near the bottom thereof and the upper end of which is provided with a funnel'intd which water may be poured, while the ipe B is also provided with a stop-cock a which may beopened to permit the introduction of water into the boiler and-which may be closed to prevent the water from being forced out again when steam ressure has been generated. In the pre erred form thereof shown, the water infthe boiler A is caused to circulate through a coil of pipe C which is disposed beneath the bottom shell of the boiler, said coil being in communication with the interior oflthe boiler near'the center thereof by a vertical portion d extending slightly above the boiler bottom, while the other end of the coil leads into the boiler as shown in (P, the intent-ion being that the circulation of the water will be es-vv tablished from the pipe dtand then through the coil and returning into the interior of the boiler through the piped, the latter being as above stated, disposed near the center thereof and directly over a heater D which may be of any suitable type, so that consequently the water in the central portion of the coil will be more strongly heated at that point and the pipe d and thus draw a fresh 'suppy from the pipe 01 and then through the coil as will be readily understood.

A stop cock f is provided in connection with the coil C so that the water may be entirely withdrawn from the boiler when dejired. 1 a

gage ass the level d f should not be high as to prevent a steamspace being left therein, such steam space being connected with a steam outlet pipe G havin a safety valve 9 and also having a thrott e b. Attention may be called at this time that the steam-space in the boiler is comparatively small because in the present instance the device is intended to produce wet or saturated steam rather than superheated and dry steam.

At a point beyond the throttle h, a flexible hose G is attached and carries at its F maybe provided to show outer end with a dish-shaped metallic head or tool I the walls of which areedged, as at i, by strips of felt. or other material extending continuously around the tool and ada ted to come into uniform'contact wit-h t e wall when the tool is applied thereto. This.

edging of felt answers for two purposes,

namely e the water in the boiler which Patented Nov. rare.v Y

bubbles will naturally rise throu h movement over the wall.

ing a series of perforations 2' through which the steam may enter into the chamber I as introduced into the channel i through a nipple G3 connected with a flexible hose G The channel 2' serves to distribute the steam entering through the nipple G for the en; tire length of the channel and consequently of the steaming chamber I.

The nipple Gr consists preferably of a pipe carrymg, at its extension projecting outside of the tool I, a collar G which is in engagement with a yoke J, the upper end of which is bifurcated to straddle the collar G and is pivoted thereon as at k, and said yoke in turn may be carried on the end of a pole J whereby the same may be directed in its It will be understood that by virtue of this construction, the tool I may rest fiat with its edges 71 against the wall irrespective of the angular position of the handle J.

By the manipulation of the handle or .polevJ, to draw the tool I over the surface of the wall, steam in comparatively wet condition will be applied to the wall surface confined Within the limits of the edging 2' of the tool, and waste of steam by virtue of escape from the steam chamberI' will be practically obviated inasmuch as. the felt edging i will naturally become saturated with Water due to the condensation of steam, so that really heat as well as moisture are deposited .by the tool upon the surface of the wall paper and the latter will be quickly moistened and softened so that it can readily be removed.

When the apparatus is to be used in low places, the pole or handle J may be removed from the socketed shank of the yoke and the steaming head or tool may then be used by grasping the yoke shank.

'lVe claim 1. In an apparatus of the character described, the combination with a boiler having an outlet pipe, of a spiral coil of pipe disposed below the boiler bottom and having its ends in communication with the.

' 2. In "an apparatus of the class described, "the combination with a boiler having an outlet pipe, of a spiral coil of pipe disposed. below the boiler bottom and having its ends in communication with the lower interior portion of the boiler near the central and outer portions thereof, a heater disposed beneath said coil, and a stop-cock connected with said coil'exteriorly of the boiler to permit the withdrawal of the water from the boiler and the coil, and a flexible hoseconnected with the outlet pipe and having a steaming head connected therewith.

3. In an apparatus of the class described, the combination with a boiler and a steam outlet pipe connected therewith, of a steaming tool comprising a hollow shell open at one side, a partition dividing the space of said shell into a steam space, and an airspace, the walls of said steam-space being edged with felt or similar material, a steampipe nipple extending into said steam-space and through the air-space, and a flexible pipe connecting said nipple with the steam outletpipe of the boiler.
